Toshiba top load washers have standard error codes. Depending on the display (2 or 3 digits depending on the model) it will either show E21 (or E23) or alternate E2 and -1 (or E2 and -3). Here's a list of most Toshiba washers error codes;
E1: Water doesn't drain in time or not at all
E21: Lid open
E23: Lid not locking
E31: Load imbalance
E32: Check E1 and/or E31
E5: No water coming in
You can try resetting to factory default by following the procedure: Power OFF, then pressing and holding the Super Spin Dry button, press power ON and it should beep 3 times.
